Shmuel Alef 20:17-19

Orthodox Jewish Bible

¹⁷ And Yonatan caused Dovid to swear a shevua again, because he loved him; for he loved him with the ahavat nafsho (with the love of his own nefesh, self).

¹⁸ Then Yonatan said to Dovid, Makhar (tomorrow) is Rosh Chodesh; and thou shalt be missed, because thy moshav (seat) will be empty.

¹⁹ And when thou hast stayed three days, then thou shalt go down quickly, and come to the makom (place) where thou didst hide thyself on the day of the ma’aseh (deed, i.e. the eventful earlier day, see v.12), and shalt remain by the even (stone) Ezel.
